What are the benefits of tinning for food tins?
Because tin mainly plays a role in preventing corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in a single material, with good corrosion resistance and ductility.
Therefore, for food safety and long-term storage, the inside of the food tin box should be tin plated. In order to prevent the iron sheet from rusting, some companies often plate tin on the iron sheet, which is the common "tinplate", which is both common and cheap.

Tinplate is an environmentally friendly packaging material that can be recycled. The printed tinplate box is coated with special food-specific paint, which can be used to safely store moon cakes, biscuits, candies, chocolates, egg rolls and other foods. If you pay attention to protection, the tinplate can be used for more than ten years and remains stainless, but if you accidentally touch the tin "clothes", the iron skin will be quickly rusted, and after a while, the entire tinplate will be covered with red-brown rust spots.

Therefore, when using tinplate, care should be taken not to damage the tin layer, nor to get damp or heat due to it. To prevent it from rusting and corrosion, the food should be tinned.
All the components of the food tin box are stamped and formed by stamping equipment. The lid needs to be made by cutting-flashing-stamping, and the can body needs to be cut-flashing-pre-bending-stamping-buckle -The back cover process is made; and the bottom is made by cutting and stamping. This is convenient for fixing when forming the iron box.
